摘  要:目的:探讨心血管磁共振钆剂延迟增强(LGE-CMR)在冠状动脉疾病(CAD)中的应用价值。方法:收集我院自2010年1月-2013年3月期间确诊为CAD且有LGE—CMR图像病例共19例(男15例,女4例,年龄范围36-79岁,中位年龄57岁),冠状动脉粥样硬化5例,冠状动脉硬化性心脏病14例,其中5例合并急性心肌梗死,5例患者有陈旧心肌梗死。由2位影像学诊断医生独立盲法评估心血管磁共振(CMR)图像中钆剂延迟增强(LGE)征象的有无、部位(心内膜下、透壁、壁间)及形态(斑点/斑片样、线条样、条片/片状),并行Kappa一致性检验。结果:2位影像诊断医生对LGE征象的有无、部位、形态的判定一致性较好(Kappa=0.908、0.733、0.724,均P〈0.05)。84.2%(16/19)CAD患者CMR可见LGE征象,且LGE主要位于心内膜下(7/16)和透壁(6/16),占81.25%(13/16);条片/片状强化占43.75%(7/16)、线条样强化占31.25%(5/16)、斑点/斑片占25.00%(4/16)。结论:LGE-CMR可以显示CAD患者心肌损害的有无及范围,可为临床医生提供心肌层面影像学信息。Objective: To explore the application in coronary artery disease with the use of late gadolinium enhancement on cardiovascular magnetic resonance (LGE-CMR) images. Methods: A total of 19 cases diagnosed as coronary artery disease (CAD) with LGE-CMR images in our hospital between January 2010 to March 2013. were accepted (15 men, 4 women, ages range from 36 to 79 years, median age 57 years), including 5 cases of coronary atherosclerosis, 14 cases of coronary atherosclerotic heart disease. There were 5 patients with acute myocardial infarction and 5 patients with chronic myocardial infarction in the group of coronary atherosclerotic heart disease. 2 radiologists evaluated whether LGE or not, LGE localizations (subendocardial, transmural, mid- wall) and LGE morphology (spot/spots, linear, patchy) independently and blindly, Kappa test for consistency. Results: LGE present/absent, LGE localization and morphology had a good consistency (Kappa=0.908, 0.733, 0.724, P all 〈0.05) between 2 radiologists. LGE signs were observed in 84.2% (16/19) CAD cases, and 81.25%(13/ 16) located in subendocardial (7/16) or transmural (6/16). 43.75% (7/16) patchy, 31.25% (5/16) lines and 25. 00% (4/16) spot/spots enhancement were seen. Conclusion: LGE-CMR is helpful to detect cardiac lesion and its range on CAD patients and also useful to identify the extent of myocardial lesions.
